Subject information obtaining apparatus, method for obtaining subject information, and computer-readable storage medium

A subject information obtaining apparatus that obtains information inside a subject by receiving an elastic wave that has propagated from the subject, the subject information obtaining apparatus comprising:

• a plurality of conversion elements configured to receive the elastic wave and convert the elastic wave into a plurality of electrical signals;
• a frequency-domain interferometry adaptive processing unit configured to execute a frequency-domain interferometry method and adaptive signal processing using the plurality of electrical signals and obtain power intensity distribution by calculating power intensity at each position on a plurality of scan lines;
• and
• a correction unit configured to execute a correction process by which variation in power intensity between adjacent scan lines in a direction that intersects with the scan lines is reduced.
